[AL. 560_Stop error (safety sub-function)]

• The safety sub-function detected an error of the stop position.
[AL. 560.1_SOS feedback speed exceeded A]
Cause
1.
The state where the absolute value of the
servo motor speed exceeds the setting value
of [Pr. PSA04 Safety sub-function - Stop
speed] continued for the time set in [Pr. PSA15
Safety sub-function - Speed detection delay
time] or longer during operation of the SOS
function.
2.
The encoder has malfunctioned.
3.
The servo amplifier has malfunctioned.
4.
There is a problem with the surrounding
environment.
[AL. 560.2_SOS command speed exceeded A]
Cause
1.
The state where the absolute value of the
speed command exceeds the setting value of
[Pr. PSA04 Safety sub-function - Stop speed]
continued for the time set in [Pr. PSA15 Safety
sub-function - Speed detection delay time] or
longer during operation of the SOS function.
2.
Take actions according to the instructions of 2. to 4. in the following item.
Page 174 [AL. 560.1_SOS feedback speed exceeded A]
[AL. 560.3_SOS feedback position exceeded A]
Cause
1.
The feedback position changed by the value
equal to or more than the setting value of [Pr.
PSA05 SOS permissible travel distance], and
the position remained out of the permissible
range for the time set in [Pr. PSA17 Safety
sub-function - Position detection delay time] or
longer during operation of the SOS function.
2.
Take actions according to the instructions of 2. to 4. in the following item.

Check/action method
Review the parameter or the operation pattern.
If the servo motor overshoots as it stops, take actions such as adjusting the
gains or setting a larger value in [Pr. PSA15].
Refer to "SS2/SOS function" in the following manual.
MR-J5 User's Manual (Function)
Replace the servo motor.
Replace the servo amplifier.
Check the noise, ambient temperature, and other conditions, and implement
appropriate countermeasures for the cause.
If there is noise, take countermeasures to reduce the noise.
Refer to "Noise reduction techniques" in the following manual.

Check/action method
Review the parameter or the operation pattern.
Set [Pr. PSA03 SS1/SS2 deceleration monitor time] to a longer time than the
deceleration time.
Check if the speed command has been input after SOS was activated.
Refer to "SS2/SOS function" in the following manual.
